Longlong：The touch screen is an open human-computer interface. It is influenced by the temperature and humidity of the environment and the static electricity of the human body by detecting the resistance and capacitance of the touch point. As common mobile phones or computers, touch and no response may occur in the northern winter dry season and the summer high temperature and humidity season in the summer. The touch or no response of the gene amplification instrument has also been reported by users. In general, the restart can be resumed. The instrument also provides a screen calibration function. The user can operate with self-help, and can enter the calibration interface in 10 seconds in the main interface, and then click on the position of the light point. If the above can not be used, we need to contact customer service to solve.

            Operation steps             

Programme 1：After the boot, the self inspection is finished, press the screen at any location for more than ten seconds, jump out of the calibration interface, and point the small cross on the screen with a needle, 5 times to OK.
